In this thread,i will be detailing my work in progress of the homebuilt rc airplane that am currently working on.

Although i had wanted to build this plane,i had started off as soon as the last material i was waiting on arrived. In my possesion,i had a Tx, Rx,servos,gyros,brushless motor,Esc and a lipo. But i hadn't a foamy.
I finally got one,so that started me into the design.

I have in mind to build an aircraft weighing not more than 900 or 1000 grammes. To achieve that,i have to take it easy on the way i choose my material.
I choosed to work with aluminuim,vero boarm,as these are very strong and light weight.

My design would be hinged on designing and building a chasis,designing the main wing,designing the rear wing and rudder. Then joining these three pieces together. The front landing gear(tyre) would sit on the chasis,but not so with the rear landing gear.

I tried to build a simple (not remote controlled) plane few days ago but it refuses to fly though I made the propeller myself so I'm thinking maybe the pro. Is not efficient enough . Ride on I'm following

If i no follow this thread, who go follow?.









2nd to follow. Lol,



carry on ma brother

Below is the chasis.

Below i am weighing the chasis. It weighs 80grammes. Although abit on the high side,it is much as i could shrink it. Anything further would compromise the structural strength of the chasis.

Now on to the landing gears. I used a bathroom slipper(rubber slipper) for making my landing gears since the are soft and could provide a shock absorber effect. This will come handy when making landings.
I started with a Gino tomato tin,cut it with a scissors so its edges are sharp enough to cut through the rubber slipper.

Taping lightly around the edges of the tin with a hammer.

After that,the whole setup is flipped over,and the taping resumes,but this time from a different side.

I'm following you bumper to bumper

Lol... Hope u guys will give me some breathing space

It continues gradually,untill the tin eats through the rubber slipper.

The sequence is reapeted twice more,to get the three required landing gears.

Next is to measure the diameters at 180 degrees,then divide it to get the radius (centre). It is from this radius that i place my pair of dividiers,then scribed out a circle that has exactly the same radius as the black cylindrical metal pipe which i shall be using shortly soon,to create a hole in the middle of the landing gears. These holes are where their bearings would sit.

Here,i am using the black cylindrical pipe to create a hole in the middle of the landing gear. This is done by slightly taping the end of the pipe with a hammer. I had had to sharpen the edges of the pipe,so it could easily cut through like a knife.

Here's the landing gear. Lying beside the landing gears are the three bearings that would sit into the middle of the tyres.

The pix below shows the bearings,installed.

I weighed the setup. It was weighing around 45gramms. Not much of some weight..
For an airplane that would have a weight of not more than 900gramms,a landing gear weighing 45 grammes isn't a problem. The problem was the strength of the landing gears. But as long as i was concerned,their strenght was superb.

It was time to install the landing gears on to the chasis.
The best method would've been to use some screw and nut to install it. But unfortunately,the circle in the middle of the bearing is too big and wide that it would swallow up any screw.
So it sure needed some little modification.

To make that mod,i would need two washers,with a circumfrence slightly larger than the middle of the bearing..
So i made them.... I ran out of aluminuim,so i switched to using a vero board.

Then i needed a screw and that little piece you see in the picture.

Subsequently,in goes one of the washers,into the screw.

Followed by the little black piece.

The screw then goes into the middile of the bearing.

Here's the other side.

The next washer comes in.

I slipped in another cylindrical plastic which i cut from somewhere. I am using it here as a spacer.

Next is to fix the landing gear in to a hole made for it in the chasis.

Here's the front landing gear installed.

I proceeded to building the elevator.

Here's the elevator,with the hinges installed.

Here's the rear wing,and thats how the elevator will sit.
